    TLDR Wound covers with α-13'-COOH from vitamin E can improve and speed up wound healing.
    The document presents a study on the wound healing effects of α-13'-Carboxychromanol (α-13'-COOH), a metabolite of vitamin E, when released from bacterial nanocellulose (BNC) wound covers. In vitro tests showed that α-13'-COOH positively influenced gene expression related to wound healing in fibroblasts and keratinocytes, as well as cell proliferation and migration. In vivo experiments using a mouse model, including a diabetic wound healing model, demonstrated that BNC wound dressings with α-13'-COOH improved wound closure times, reduced scar formation, and enhanced histological features. The study indicates that α-13'-COOH-loaded BNC could be an effective treatment for wounds, especially in diabetic conditions where healing is typically slower. The number of mice used in the study varied, with some groups having 4 and others having 5 to 9 mice. The findings suggest that the controlled release of α-13'-COOH from BNC wound covers could be beneficial for complicated wound management due to its anti-inflammatory effects and ability to promote better and faster healing.

      FCE 28260: A Forgotten 5α-Reductase Inhibitor

      community FCE 28260: A Forgotten 5α-Reductase Inhibitor

      in Research  330 upvotes 2 months ago
      FCE 28260 (PNU 156765), an under-explored 5α-reductase inhibitor, showcases promising results in research by Giudici et al., outperforming well-known treatments like Finasteride in reducing the conversion of testosterone to DHT. Its superior efficacy, demonstrated through lower IC50 values in both natural and human recombinant enzyme studies, suggests it could offer more effective management of DHT-related conditions. Additionally, its lower molecular weight hints at better potential for topical application, potentially offering advantages in treating conditions such as androgenic alopecia. Despite its potential, it has not advanced in development, possibly due to financial limitations, leaving its therapeutic prospects and side effect profile largely unexplored.

      Scalp biopsies are crucial for diagnosing hair loss conditions like Diffuse Unpatterned Alopecia (DUPA) and retrograde hair loss, as treatments like finasteride and dutasteride may not be effective if other conditions are present. Combining PPAR-GAMMA agonists with retinoids could improve treatments for conditions like Lichen Planopilaris.

      community Bile Acid-Mediated DHT Dysregulation Hypothesis

      in Research/Science  13 upvotes 2 weeks ago
      Elevated bile acids can inhibit the enzyme AKR1C2, leading to increased DHT levels, which may accelerate hair loss in those predisposed to androgenetic alopecia. Treatments mentioned include topical minoxidil and finasteride.

      community SAFFLOWER OIL good alternative for Minoxidil?

      in Treatment  1 upvotes 4 years ago
      Safflower oil is suggested as an alternative to minoxidil for hair growth, with benefits including scalp conditioning and hair strength enhancement. Studies indicate it may also reverse scalp dermatitis, alopecia, and prevent premature grayness.
